He said: "HMS Valiant is a great name, for our ships and submarines have been valiant for 200 years. We are dedicated to making sure our deterrent is the best and strongest in the world." The name 'Valiant' comes from the Valiant class of nuclear-powered fleet submarines in service with the Royal Navy from the mid-1960s until 1994. The original Valiant submarine was built and commissioned at the Barrow shipyard and launched in December 1963. |
